| 摘 要： | 用差示扫描量热法(DSC)研究了不同共混比例PEN/PET共混物的熔体结晶行为,并进行了等温结晶动力学测定。结果表明:随着两种组分向中间比例(50/50)靠近,共混物的熔融温度越低,结晶速率也越慢。

| Abstract: | The crystallizing behavior and crystallization kinetics of poly(ethylene terephthalate)/poly(ethylene 2,6-naphthalate) blends were investigated by differential scanning calorimetry as functions of crystsllization temperature, blend composition. Isothermal crystallization kinetics were evaluated in terms of the Avrami equation. The results indicate that as the proportion of PEN/PET approach 50/50 the crystallization rate of blends become slower. |
